The Series UR7000 reel is designed to aide in the servicing/dispensing of Diesel Emissions Fluid (DEF) on-board systems for late model diesel engines. Automotive Diesel Emissions Fluid (DEF) is injected into the vehicles' exhaust stream to "scrub" nitrogen oxide (NOx) from the diesel exhaust.

Diesel Emissions Fluid (DEF) is the only technology available that can remove enough NOx from diesel exhaust to comply with strict new limits imposed by the U.S. that will take effect in January 2010. These reels are an integral part in Diesel Emissions Fluid (DEF) dispensing equipment found in truck stops, service stations and garages.
